Obtusifolin improves cisplatin-induced hepatonephrotoxicity via the Nrf2/HO-1 signaling pathway.

Cisplatin (CIS) is a highly effective chemotherapeutic drug, but one of its most serious side effects is hepatonephrotoxicity, which varies based on its dosage and duration of use. Previous studies have reported that obtusifolin (OBS) exhibits several pharmacological effects, including antioxidant and antidiabetic activities. In this study, we investigated the protective effects of OBS against CIS-induced hepatonephrotoxicity.

Syringaldehyde Mitigates Cyclophosphamide-Induced Liver and Kidney Toxicity in Mice by Inhibiting Oxidative Stress, Inflammation, and Apoptosis Through Modulation of the Nrf2/HO-1/NFκB Pathway.
